Than it's K8 dualcore, which has TSC register drift problem and Opensolaris isn't able to support powernow on it. The latest AMD CPUs has TSC register updates stable accross frequencies. > Solaris (old version) is installed on my Pentium 4 desktop ( I guess > here only the Intel's speed test v1 works ). > If that P4 isn't one of the oldest P4 core, then speedstep should work on it. You can test it easily, just download OpenSolaris LiveCD, boot from it and check output from: kstat -m cpu_info | grep supported_frequencies_Hz If there is more than one frequency, you have hardware for Tesla projects immediately :-) > Regards , > Sathvik > Best regards, Milan > > On Wed, Nov 19, 2008 at 8:41 PM, Milan Jurik <Milan.Jurik at sun.com> > wrote: > Hi, > > "ps: I have a AMD dual core processor but if any specific h/w > requirements exist, please let me know." > > > There could be problem.
